Abstract

The utility model relates to a foldable umbrella. Eachgroup of umbrella skeleton frames of the foldable umbrella is provided with at least one pair of umbrella skeleton segments which stretch and move in a parallel (or almost parallel) mode, wherein, a guided umbrella skeleton segment is made of steel wires and is directly formed with a bent part used as a guide component, so that the weak guided umbrella skeleton segment can move by guiding and is supported on a main guide umbrella skeleton segment to strengthen the anti-pressure and anti-pulling rigidity of the main guide umbrella skeleton segment. The guide component of the guided umbrella skeleton segment (2) forms a small ring (2 e, 2 e) shape, and uses corresponding safety hooks (2 f, 2 g) to surround the cross-cutting mold surface (Q) of the main guide umbrella skeleton segment (1). The surrounded components make the small ring hang on the main guide umbrella skeleton segment (1) or be taken from the main guide umbrella skeleton segment through a path (P) formed by a separating seam between the two safety hooks (2 f, 2 g).

Description

Foldable umbrella

The present invention relates to a kind of folded umbrella, each group of its umbrella frame frame all has at least one pair of extends parallel parallel to each other or approximate and movably is subjected to pilot chute bone section, and wherein the umbrella frame section of being led on leading umbrella frame section is the guide member that is made of steel wire and moved by pilot chute bone section by a bool conduct that directly forms thereon.

The folded umbrella of this class formation is at U.S. Patent bulletin 4,966, given open in No. 143761, No. 180 and the Taiwan patent gazette.Two stretching, extensions parallel to each other are all arranged in this two example and movably be subjected to the stock of pilot chute bone section as the connecting rod parallel-crank mechanism.In order to access the desirable folding thing that dwindles when collapsing umbrella, control stick is to be made by finer wire, and a spiral coil is housed on this steel wire in addition, by this circle control stick can be supported on the firm parallel bar movably.At U.S. Patent bulletin 4,966, the lasso that spiral coil is described to become flexible in No. 180, then being illustrated as in No. 143761, Taiwan patent gazette is to be made of the multi-head spiral line.In this two example, described lasso or spiral coil can not only make weak tiny but still control stick that can bear pressure and pulling force be supported on the parallel bar and reinforce, and can also save a special-purpose guide element that separates from cost saving, as U.S. Patent bulletin 4, sleeve guide member among 966, No. 180 Fig. 1, or in other modification as U.S. Patent bulletin 4,739, Fig. 4 of No. 783 or 4,676, Fig. 5 of No. 262.Guiding in particularly above-mentioned last patent gazette, owing to be that the method for using the material to the transversal profile of parallel bar to push moves thin control stick thereon, thereby do not need to set up separately parts equally.But this extruding can make this connecting rod make undesirable weakening, so this scheme that weak control stick is supported and guide is unpractical.But above-mentioned according to U.S. Patent bulletin 4,966, No. 180 and Taiwan patent gazette adopt for 143, No. 761 lasso and spiral coil to support and the method guided but is irrational.Rely on this guide member, the control stick of the weakness that is made of finer wire should be able to reach one can be played the support of reinforcement effect and have necessary tension and measuring body rigidity.Rely on said snare formula or spiral coil formula guide member simultaneously, the guide member of support also should be made quite cheap and easily.But these lassos or spiral turns produce the opposite effect that does not meet production requirement, because the nature of these guide members is that the pulling force and the pressure that are applied to control stick one end simultaneously have at least major part not transmit to pulling force and pressure damping and elimination linearly.Will make the function generation problem of whole umbrella like this.

The objective of the invention is to make the defective of this respect to be remedied and make improvements for this class umbrella that has illustrated, particularly will make the manufacturing of the guide member that is sleeved on the weak umbrella frame section on the parallel umbrella frame section be tending towards reasonable but still can make unlikely the suffering damage of function that is subjected to pilot chute bone section original, these guide members are also wanted and can be installed and removed easily in addition.

According to the present invention, above-mentioned task is to solve like this, be subjected on the pilot chute bone section the little ring that is shaped as the bool of guide member, this little ring is made ring-type with the auxiliary catch of face-off to the cross section of leading umbrella frame section and is surrounded, at that time this besieged itself can be by dividing gap formed passage between the face-off auxiliary catch, be placed in little ring on the leading umbrella frame section or take off from it.

So just can draw a kind of structure and conform with practical folded umbrella, it can the pilot chute bone section function of being made by steel wire that is subjected to that itself is weak correctly be supported on the leading parallel umbrella frame section, directly adopts little ring to guide, and does not damage the function of resistance to compression and tension.Simultaneously need only small number of operations, just can install and remove simply.By little ring the length direction that the umbrella frame section of the weakness of being led is crossed leading umbrella frame section simply is clamped on the leading umbrella frame section.The effect here of little ring is just as a clip or clamp, and it surrounds the transversal profile of leading umbrella frame section, keeps necessary freedom of movement, reliably can not run away across length direction at umbrella frame, and can on this length direction, not surrender.Therefore the umbrella frame section of the weakness of being led can obtain necessary support and reinforcing from leading parallel umbrella frame section, also can obtain necessary resistance to compression and tension rigidity simultaneously, therefore be applied to the pressure and the pulling force that are subjected on the pilot chute bone section and can be absorbed again, but function correctly can be passed.

The of the present invention a kind of effective embodiment that little ring is loaded onto with elastic method and keep be little ring is made two can be separated from each other, the ring of shape such as spring clip, for little ring is clamped on the leading umbrella frame section, auxiliary catch is made as clamp, closed up the also appearance of expansible spring dop at that time.

One corresponding effectively improves is closed up by little ring between two terminations of stretching to both sides respectively in the above and will close up (Fig. 5) below as clamp with the spring mouth that can strut of little ring face-off.

Another modification of the present invention can make the resistance to compression of little ring and tension rigidity improve, and the auxiliary catch of at that time little ring is embedded to the transversal profile interior (Fig. 7) of leading umbrella frame section.

The another kind of effectively embodiment of little ring profile intersects two auxiliary catches to be interlocked with hooking.

Little ring guide member also has a kind of effective embodiment little ring to be made dicyclo and arrange the hook tongue with straight line protuberance between two auxiliary catches.

Following the present invention will illustrate in detail with a plurality of illustrated embodiments.Wherein:
